A separate system with ATF would work fine if you wanted to use a worse
lubricant, add complexity, failure modes, weight, space requirements, and power
consumption.

Tracy,
Ian brough up a point that could also apply to the re-drive. Since
the planet ass'y was originally designed for lubrication with ATF, is
there any particular reason why it couldn't be run as a closed system with
a "scavage" pump circulating ATF, instead of using engine
oil?
Dunno if there's any advantage to the ATF, for that
matter, but I thought I'd ask.
Dale (to whom the thought just
occurred that this may have already been discussed - some years ago - and
could be in the archives.)
